Update the default version of GCC used in the Ports Collection from
GCC 4.6.4 to GCC 4.7.3. This entails updating the lang/gcc port as
well as changing the default in Mk/bsd.default-versions.mk.

Cleanup unmaintained ports in the misc category:
- Trim Header
- Convert to OptionsNG
- Prefer DISTNAME to DISTFILES
- Reorder variables
- Fix comments (don't include leading article)
- @unexec rm must not cause failure
- Tabs, not spaces
- Single space for WWW
- Pet portlint
- etc.
In a few cases the option DOCS was used to control installation into EXAMPLEDIR.
I opted to keep the existing logic of the port in these cases.

Presenting GNOME 2.20.1 and all related works for FreeBSD. The official
GNOME 2.20 release notes can be found at
http://www.gnome.org/start/2.20/notes/en/ . Beyond that, this update
includes the new GIMP 2.4 (courtesy of ahze).
The GNOME 2.20 update also includes a huge change in the FreeBSD GNOME
hierarchy. We are now using the more standard DATADIR of ${PREFIX}/share
rather than ${PREFIX}/share/gnome. The result is that fewer patches and
hacks are needed to port GNOME components to FreeBSD. This will mean some
user changes may be required, so be sure to read /usr/ports/UPDATING for
more details.
This release and the things we accomplished in it would not have been
possible without mezz's crazy idea to collapse DATADIR, and his persistence
to make it happen successfully. Ahze and pav also deserve thanks for
